The analysis of percolative fragmentation for noncatalytic gas-solid reactions, with special emphasis on gasification and combustion of carbonaceous materials, is presented. The description of pore surface area and pore surface enlargement during reaction is based on the random pore model developed

β¦ Synopsis
We consider a percolation model which consists of oriented lines placed randomly on the plane. The lines are of random length and at a random angle with respect to the horizontal axis and are placed according to a Poisson point process; the length, angle, and orientation being independent of the underlying Poisson process. We establish a critical behaviour of this model, i.e., percolation occurs for large intensity of the Poisson process and does not occur for smaller intensities. In the special case when the lines are of fixed unit length and are either oriented vertically up or oriented horizontally to the left, with probability p or (l-p), respectively, we obtain a lower bound on the critical intensity of percolation.
